FLOOB-SCBUBBING DEVICE.

Application filed March 28, 1925.

F0 (277 11171 cm it may concern:

Be it known that I, Amen J. GRABILL, a citizen of the United States,residing at lmler, in the county of Bedford and State of Pennsylvania,have invented certain new and useful Improvements in Floor-ScrubbingDevices, ofwhich the following is a specification, reference being hadto the accompanying drawings.

This invention relates to floor scrubbing devices, and particularly tofloor scrubbing devices in the nature of tanks mounted upon wheels andhaving scrubbing mops connected thereto.

The general object of the invention is to do away with the necessity ofscrubbing floors by hand, which is most tiresome and back-breaking work,and to provide a ready, easy and simple means for scrubbing floors whichcomprises a tank adapted to contain water, a mop holder mounted upon thetank and movable therewith, the tank being mounted upon wheels and thetank being provided with a spigot or tap whereby the water may bedischarged upon the mop or on the floor itself in measured quantities.

A further object is to provide a device of this character having apivoted handle so that it may be readily pushed back and forth over thefloor to cleanse the same, and which is provided with a relatively largeopening in its top normally closed by a cover which may be used tocatch. the water wrung from a drying mop.

A still further object is to provide improved means for supporting themop, this means being particularly so constructed that two mops may beused or held in place.

Other objects have to do with the details of construction andarrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the accompanying drawings, wherein Figure1 is a top plan view of a scrubbing machine constructed in accordancewith. my invention;

Figure 2 is a longitudinal vertical section on the line 22 of Figure 1;

Figure 3 is a perspective view of the loweror wheel-supported frame;

Figure 4c is a perspective view of the tanksupporting frame;

Figure 5 is a perspective view of the mopsupporting frame;

Figure 6 a perspective view of the cl mp whi ngages th m p;

Serial No. 19,139.

Figure 7 is a perspective view of two mops showing the manner in whichthese are disposed within the frame.

Referring to these drawings, it will be seen that I have provided asupporting frame, designated generally 10, having wheels 11.. Theforward end of the wheeled frame 10 is provided with two wheels 11. Thisframe is composed of longitudinal members 12 connected by cross braces13. The handle 14 is connected to the frame 10, as will be described.

Detachably supported upon the frame 10 is a tank, designated generally15, which, as illustrated, is rectangular in section and plan and whichat its rear end is provided with a tap 16 whereby water may bedischarged upon the mop. This tank may be formed in one pieceor in aplurality of pieces, and preferably the tank is provided with arelatively large opening-1r at its top having upstanding walls, whichwalls may be outwardly flared, and this opening is normally closed by alid 18. This tank is held to a tank-supporting frame 19 composed of thelongitudinally extending membe'rs 20 and the cross braces 21. Thesebraces 21 extend beyond the longitudinally extending side pieces 20 andthe tank is held upon this frame 19 by means of U-shaped straps 22 whichare preferably made of galvanized iron, the lower ends of these strapsbeing angularly bent, so as to rest upon the projecting ends of thebraces 21 and be bolted thereto. These straps hold the tank firmly inplace but permit its removal when necessary. The rear end of the frame19 is formed by a transversely extending angle iron 23 andthe forwardend of the frame carries a transversely extending brace 24: to which thehandle 14; is pivoted, this'ha-ndle being bifurcated or forked so as toprovide two arms which are hingedly connected to the brace 24, thuspermitting the handle to be moved vertically.

Coacting with the angle iron 23 is a pair of flat bars 25 which areangularly bent at one end and which are bolted to the angle iron 23,these two supporting bars 25 extending downward and being provided witha plurality of bolt apertures. Bolted to these supporting bars 25 is ascrubber supporting frame consisting of members 26 which are angularlybent to provide vertical portions bearing against the bars 25 and boltedthere to and a horizontal portion having transversely extending braces27 having bolt holes in their extremities. Bolted over these transversesupports 27 is a rectangular frame 28 having bolts at its corners whichpass through the projecting ends of the members 27 and the mop 29 isheld between these transverse members 27 and the frame 28, with the yarnon the mop extending downward so as to come in contact with the floor. Adouble mop is used, as shown in Figures 2 and 7, with the webs of themop disposed over the cross pieces 27 and with the projecting yarnsextending downward between the cross pieces 27 and downward over theedge of the cross pieces. By having two mops, the strings of the mops donot have to be so long and yet the same results are obtained and the mopas disposed keeps inplace better by beingdivided than if it was onelarge mop. With this construction the mop may be raised or lowered toany desired height so as to bear upon the floor either lightly orheavily and the spigot 16 will discharge upon the mop itself.

In the use of this device, the tank is filled with hotsoapy water to anyextent desired, the scrubber is then rolled onto the floor where it isto be used, and a small amount is turned on by means of the tap. Thescrubher is then oscillated backward and forward over the floor so thatthe mop will thoroughly wash and scrub the floor. After the floor hasbeen scrubbed in this manner and dried, another mop may be used for thepurpose of getting up this water and giving a final finish to the floor.This mop may be wrung out through the opening 17 in the top of the tank.It will be seen that this will eliminate the necessity of carryingbuckets of water and eliminate any tendency to slop dirty water on thefloor, and that by its use just the right amount of water may bedischarged upon the floor from time to time as it is needed, and whenall is done the tank maybe readily wheeled out of the room instead ofhaving to carry buckets of dirty water out. It is particularlyconvenient for charwon'ien and the like who have to scrub linoleum,marble floors and floors covering a large area.

Obviously the tank may be constructed so as to suit heavy work or lightwork and a heavy mop or alight mop may be secured by simply setting thescrubbing -1nop a little higher or a little lower. Preferably the wheelswill be rubber-tired and the tank will be made ,of galvanized metal.

I claim 1. A scrubbing device of the character described comprising awheeled supporting frame, a tank .detachably mounted upon the frame, ahandle whereby the supporting frame may be shifted, depending membersmounted upon the forward end of the frame, a mop support adjustablymounted upon said depending members for vertical adjustment, the mopsupport comprising a lower frame, and an upper frame clamped upon thelower frame and a mop engaged between said lilbi named frames.

2. A scrubbing device of the character described comprising a wheeledsupporting frame, a frame resting upon the supporting frame anddetachably bolted thereto, a handle pivoted to the last named frame, atank resting upon the second named frame and having a controllabledischarge device at its forward end, straps engagin over the tank andbolted at their ends to the second named frame, a mop-supporting meansmounted upon the second named frame and extending downward therefromtoward the floor and vertically adjustable, and a mop carried by the mopsupporting means.

3. A floor scrubbing device of the character described comprising awheeled supporting frame having longitudinal members and transversemembers, wheels carried thereby, a frame resting upon the supportingframe and having longitudinal and transverse members, the longitudinalmembers being bolted to the supporting frame and the transverse membersprojecting out beyond the longitudinal members. a tank resting upon thesecond named frame, yokes passing over the ends of the tank anddetachably bolted to the projecting ends of the transverse members onthe second named frame, said tan k having a discharge spigot, a mopsupport carried by the second named frame at one end thereof and beneathsaid spigot, and a mop on said mop support.

In testimony whereof I hereunto affix my signature.
